Do I still need to worry about LegacyExchangeDN when creating a dist group in Exchange 2007?

Question

I'm extremely new to Exhange and have a programming task to create distribution groups.

The method I am using is

public GroupPrincipal CreateDistributionGroup(string groupName, string displayName, string description, GroupScope groupScope, 
            string emailAddress, string exchangeDN)
        {
            GroupPrincipal distGrp = this.CreateGroup(groupName, description, groupScope, false);

            this.SetGroupAttribute(distGrp, GroupAttribute.MailNickName, groupName);
            this.SetGroupAttribute(distGrp, GroupAttribute.DisplayName, displayName);
            this.SetGroupAttribute(distGrp, GroupAttribute.ReportToOriginator, true);
            this.SetGroupAttribute(distGrp, GroupAttribute.Mail, emailAddress);
            this.SetGroupArrayAttribute(distGrp, GroupAttribute.ProxyAddresses, "SMTP:" + emailAddress);
            this.SetGroupAttribute(distGrp, GroupAttribute.LegacyExchangeDN, exchangeDN);
            this.SetGroupAttribute(distGrp, GroupAttribute.MsExchRecipientDisplayType, 1);

            return distGrp;
        }

Notice that one attribute that gets set is the LegacyExchangeDN. Can I safely ignore this in Exchange 2007, or is it still required?

LegacyExchangeDN is used by Outlook2000 clients (IIRC) and for other Outlook clients that cached a group before Exch 2007 was in place. Which is to say, if you don't have 11 year old Outlook running around, you shouldn't need to set that for new groups.

Thank you for the explanation. I ignored that property and the group creation went through just fine. – JL. Apr 04 '11 at 20:06
